Trick Flow Cylinder Head Upgrade For 2 Valve 4.6L Ford Modular Engines - 453HP 2V 4.6 - Speed Parts Testing

When we first had the idea of building a Junkyard Jewel out of Ford's much beleaguered but widely produced 2V 4.6L (Apr. '08), we knew our biggest stumbling block was going to be the heads.When we first had the idea of building a Junkyard Jewel out of Ford's much beleaguered but widely produced 2V 4.6L (Apr. '08), we knew our biggest stumbling block was going to be the heads. Even with 46mm oversized valves in '99-and-later Power Improvement (PI) heads and the most extensive porting magic Ford Performance Solutions could work, we were still barely cracking 200 cfm of airflow. While that was a significant improvement over stock, it was nowhere near the breathing room we wanted for our small-displacement, SOHC engine. Wehn we first built our 4.6 there were no aftermarket heads available. That has changed, thanks to Trick Flow Specialties (TFS).
